So far, all the games that use Amiibo, the Skylanders-like toys that unlock in-game bonuses, are published by Nintendo. But the upcoming One Piece: Super Grand Battle! X for 3DS will be the first third-party game to include Amiibo support. The toys will unlock costumes for the various fighters that transform them into the same Nintendo characters. So tapping the Mario Amiibo will give main character Luffy a Mario outfit. These aren’t simple reskins, but fully-designed costumes that look more creative than I’d expect. The trailer below shows off the Smash Bros.-like fighting action, with the Amiibo details showing up near the end.

One Piece: Super Grand Battle! X hasn’t been confirmed for a US release yet, but some previous One Piece games have been released here, so it’s certainly possible. One caveat: only the New 3DS (currently unreleased in the US) includes Amiibo support, so any older 3DS models will require an adapter (also currently unreleased).
